For the base:
-Paper towel or toilet paper roll tube
For the flowers:
-Satin/organza/shiny polyester fabric
-A wide pillar candle
-hot glue gun
Step 1: Base construction
To make the base, wad up newspaper sheets into a ball until it's the size you want. Once you're happy, cover it with enough masking tape that the ball holds its shape.
Rip up more sheets into large strips, and prepare a paste of flour and water. I didn't measure it; I added flour until it wasn't runny.
Place a strip on the ball, and use your hands to coat the strip with paste.
Repeat until you have a few layers of strips, then set the ball aside to dry.
Remember to rotate the ball every few hours or so, or you'll end up with a mushy spot.
Once it's dry, cut a hole in the base, pull out the newspaper, and tape a paper towel or toilet paper roll on - it'll act as your grip.
